Slice 10537 Seam Ripper Blades,Ceramic,White,Pointed Tip

I bought the knife with the round-pointed one. They are OK, but don't under small stitches. This replacement with the sharp-point is really SHARP. it goes under the very small stitches and cut it with ease. It is made of ceramic and will not rust. This is my very handy tool now. The price is high, but may last for long time. The replacement blade doesn't come with instruction. You have to visit their site.

I really like these blades. They work well but the tips are very delicate and can break off, making it harder to cut threads cleanly.

Perfect for tight seams. Nice and sharp. Easy to use! I’ll never use the old standard seam ripper again.

Love how easily it cuts through my clay!

Unfortunately, steel blades are definitely sharper and thinner, easier to slide under stitches and use as seam rippers, than these ceramic ones,
